ul - do underlining
ul [-i] [-t terminal] [filename...]
ul reads the named filenames (or the standard input if none are given)
and translates occurrences of underscores to the sequence which indi-
cates underlining for the terminal in use, as specified by the environ-
ment variable TERM. ul uses the /usr/share/lib/terminfo entry to
determine the appropriate sequences for underlining. If the terminal is
incapable of underlining, but is capable of a standout mode then that
is used instead. If the terminal can overstrike, or handles underlining
automatically, ul degenerates to cat(1). If the terminal cannot under-
line, underlining is ignored.
-t terminal Override the terminal kind specified in the environ-
ment. If the terminal cannot underline, underlining is
ignored. If the terminal name is not found, no under-
lining is attempted.
-i Indicate underlining by a separate line containing
appropriate dashes `-'; this is useful when you want to
look at the underlining which is present in an nroff(1)
output stream on a CRT-terminal.
ul returns exit code 1 if the file specified is not found.

nroff usually generates a series of backspaces and underlines inter-
mixed with the text to indicate underlining. ul makes attempt to opti-
mize the backward motion.
